How is obstructive sleep apnea diagnosed with a sleep test?
Short answer
Obstructive sleep apnea is diagnosed with a sleep test, either at home or in a sleep lab. The test records breathing and oxygen levels; a lab study also measures sleep stages. A physician chooses the right test based on your symptoms, health history, and risk of other sleep or breathing problems.
A medical review is the first step in checking for obstructive sleep apnea. Your physician asks about snoring, witnessed breathing pauses, sleepiness, and other health conditions. Screening questions can estimate risk, but they do not confirm the diagnosis. A watch, phone app, or oxygen reading alone is not enough.
A home sleep apnea test records breathing signals and blood oxygen while you sleep in your own bed. It is mainly used for certain adults with signs of moderate or severe OSA who do not have complicating health conditions. It is not the right test for everyone.
An overnight sleep lab study records more information, including brain activity, sleep stages, breathing effort, and heart rhythm. It may be needed if you have certain heart, lung, nerve, or other sleep problems.
A negative or unclear home test does not always rule out OSA. If concern remains, a lab study may be needed. A licensed physician in your state reviews the findings and decides which treatment is appropriate.
